The more you think about it, the easier it is to see just how bananas it is that Katie got this good, this fast. Remember, she actually won gold already before these games at the 2012 Olympics in London.

Now she's just taking things to another level. On Wednesday, she entered the pool during the 4x200m relay final with a deficit. She would later exit with an insane lead for the US.

As for Phelps, he's obviously still doing his thing, on course to add six more medals to his name, just as he'd done before he met Katie Ledecky for the first time.
